Description of key information

Waiver. In accordance with Column 2 of REACH Annex IX, the soil simulation test (required in Section, 9.2.1) does not need to be conducted as direct or indirect exposure of soil is negligible.

Key value for chemical safety assessment

Additional information

Waiver. In accordance with Column 2 of REACH Annex IX, the soil simulation test (required in Section, 9.2.1) does not need to be conducted as direct or indirect exposure of soil is negligible. Exposure potential is expected to be negligible since the substance is only used as a monomer to make polyurethane mouldings. There is negligible exposure to aqueous process streams during downstream use and hence also negligible emission to a sewage treatment plant. Exposure of soil is hence also considered negligible. The chemical safety assessment does not indicate any need to investigate further the degradation of the substance and its degradation products. Also, the substance’s low hydrophilicity is demonstrated by the very low log octanol-water partition coefficient (Log Kow) of 0.41 at a neutral pH indicating low adsorptive potential. Therefore, no additional degradation testing is necessary based on negligible exposure.
